AngelJ: thanks! I really need the tips to improve, some things I just don't see until someone makes a remark about it.
I made some eyelids. A bit hard if you didn't plan for it, but ZBrush' progressive subdivision levels got me there eventually. The eye corners need more work: I just found a picture in a anatomy drawing book that might help me with it.
Also I plucked up the courage to add yet more flesh to the lips. I do think it's closer to the mark. I never realized Cutter had such a tick underlip! Shows that really observing is much different then simply looking at a picture.
Next stop: the nose. It doesn't look right yet. Wendy Pini just drew a few lines and there is a nose. In 3D you have to examine every curve and angle...
